Note!
Due to the high diffusion rate of ammonia, it is recommended to use the FMP45 with gas-tight
bushing for measurements in this medium.
Function "Distance/Measured Value"(008)
The measured distances from the reference point to the product level and the interface are shown.
Check whether the values correspond to the actual distances. The following cases can occur:
• Distances correct -> continue with group selection
• Distance to level incorrect -> empty tank/bypass and perform mapping over the entire probe
length (see BA366F - "Description of Device Functions").
• Distance to interface incorrect -> check entry for "Medium Prop." (003).
